- 折り畳まれたエアバッグ及び該エアバッグを膨張させるインフレータを備え、該エアバッグの基端側に配置された該インフレータの噴出ガスにより該エアバッグはその先端側が該基端側から遠ざかる方向に膨張するエアバッグ装置であって、
該エアバッグとして、左側において膨張する左半側エアバッグと、右側において膨張する右半側エアバッグとを有するエアバッグ装置において、
該左半側エアバッグ及び右半側エアバッグは、それらの先端部同士が非連結状となっており、これにより、膨張した状態において該左半側エアバッグ及び右半側エアバッグの先端部同士の間に、乗員に向って開放する空間部が形成されるよう構成されており、
該左半側エアバッグと該右半側エアバッグとの膨張方向の途中部分同士が連結されており、
該左半側エアバッグ及び右半側エアバッグは、それぞれ、1次折り畳みされることにより前後方向に細長い1次折り畳み体とされ、次いで、該左半側エアバッグ及び右側エアバッグの連結部分よりも膨張方向先端側同士を離反させ、かつ該連結部分よりも該基端側を前後幅が小さくなるように折り畳むことにより2次折り畳み体とされ、その後、左右幅を小さくするように3次折り畳みされることにより最終折り畳み体とされていることを特徴とするエアバッグ装置。 - 請求項1において、該左半側エアバッグと右半側エアバッグとの上下方向の途中部分同士が連結されていることを特徴とするエアバッグ装置。
- 請求項1において、該左半側エアバッグと右半側エアバッグとの上部同士及び下部同士がそれぞれ連結されていることを特徴とするエアバッグ装置。
- 請求項1ないし3のいずれか1項において、該2次折り畳み体の一部がプロテクタークロスにより被包されていることを特徴とするエアバッグ装置。
- 請求項1ないし4のいずれか1項において、該最終折り畳み体の一部がプロテクタークロスにより被包されていることを特徴とするエアバッグ装置。
- 請求項5において、前記2次折り畳み体を被包するプロテクタークロスと最終折り畳み体を被包するプロテクタークロスとが一連となっていることを特徴とするエアバッグ装置。
- 請求項1ないし6のいずれか1項において、
該左半側エアバッグ及び右半側エアバッグの膨張時における各々の左右方向の幅員を規制するために、該左半側エアバッグ及び右半側エアバッグの左右の側面を構成するパネル同士の間に吊紐がそれぞれ架設されていることを特徴とするエアバッグ装置。 - エアバッグを折り畳んで請求項3に記載のエアバッグ装置のエアバッグ1次折り畳み体とする折り畳み方法であって、
細長いプレートをエアバッグ前後方向に延在するように左半側エアバッグ又は右半側エアバッグの外面に当て、
該プレートの長側辺に沿って該プレートを取り巻く方向に左半側エアバッグ又は右半側エアバッグを複数回折ることにより1次折り畳み体とし、
その後、この1次折り畳み体から該プレートを引き抜くことを特徴とするエアバッグ折り畳み方法。
